If I’m not mistaken, the N100 runs on a Raspberry Pi Compute Module 4 (CM4). There are multiple reports that certain CM4 and Raspberry Pi 4 batches have issues with date synchronization. I own two units, one works flawlessly, while the other consistently throws date misalignment errors.
So stating that Volumio is having issues pulling the date is not fully accurate.
The latter can be easy resolved by running a simple startup service, which does miracles.
And if you dislike google, you can also use:
ExecStart=/bin/bash -c "sleep 30; /usr/bin/sudo /bin/date -s \"$(/usr/bin/curl -s --head head http://time.is | grep ^Date: | sed 's/Date: //g')\""
